What is Fatbag?
1.
A medium pizza, rolled up and deep-fried. It is officially called a pizza roll. Usually ordered when intoxicated. The favorite food of drunk St. Lawrence University students. If eaten sober, the first few bites tend to taste quite delicious. The same can't be said about the last few bites. THE ultimate diet killer, hence the name "fatbag."
"I was so drunk last night, I called Sergi's and ate a whole fatbag by myself."
